(Version 1.8.7)

I(POWER)MAC  addendum:

it seems that there has been a problem in my previous post.

The URL from where to download the newest Java Embedding Plugin is the following: http://sourceforge.net/projects/javaplugin/files/  
(Version 1.6.10)

I(POWER)MAC  For "Snow Leopard" users: download from here the newest Java Embedding Plugin, and Java will work perfectly.  
(Version 1.6.10)

I(POWER)MAC  The annoying bug that was present in the previous release has been removed, and now the sound works again fine.  
(Version 11.5.0.596)

I(POWER)MAC  regarding to the package, more correctly than "official" we should say "binary": indeed also source code is "official" ;-) .  
(Version 2.2.4)

I(POWER)MAC  In the "System requirements" page of Silverlight (see here: http://www.microsoft.com/silverlight/resources/install.aspx?v=1.0#sysreq) is clearly specified that Silverlight 2.0 is only for MacIntels.

I don't know who has posted this release of Silverlight, but he/she has posted wrong infos about it.  
(Version 2.0.40115)

I(POWER)MAC  Safari Tidy plugin 0.2.6 isn't compatible with Safari 3.2.1.  
(Version 0.2.6)

I(POWER)MAC  1) click:

1.1) here for the uninstaller for Panther and above

or

1.2) here for the uninstaller for Jaguar and below;

2) then click here for Flash Player 9.  
(Version 10.0.22.87)

I(POWER)MAC  ECADEE: open Java Preferences and rearrange the various versions moving to upper place the J2SE 6.0.

SKALLAGRIMSON: Java 1.6 is only for Intel Macs.  
(Version 5.0.11)

I(POWER)MAC  simply amazing: it does exactly what I need. A terrific little piece of software.  
(Version 0.0.5b)

I(POWER)MAC  there's nothing to fix:

- by one side: "This release of J2SE 5.0 and J2SE 1.4.2 supports all Intel and PowerPC-based Macs. Java SE 6 is available on 64-bit, Intel-based Macs only." (Description);

- by other side: "64-bit Intel Mac (Core 2 Duo or Xeon) for Java SE 6" (Requirements).

Both the above sentences say the same thing.  
(Version Update 2)

I(POWER)MAC  for PPC users: OpenOffice 3.0b2 is also available for this platform; click here and find your localized version in the second part of the list.  
(Version 3.0b2)

I(POWER)MAC  Indeed this software seems to be especially conceived for those which have a Mac that doesn't allow to install Leopard - and, consequently, they don't have Quicklook -.  
(Version 1.0.8)

I(POWER)MAC  Eigenmath is what Apple's Grapher should be, at least in my wishes.  
(Version 136)

I(POWER)MAC  read here for more info about Spotlight importers and thier scope.  
(Version 1.0)

I(POWER)MAC  try to delete first the .plist file, then the other files (.app file and .dmg file), and finally to remove the icon from the dock.  
(Version 1.5.1)

I(POWER)MAC  really useful piece of software. It would be nice if a future version will allow users to rearrange the list of search engines as it is already possible with Firefox.  
(Version 1.0b6)

I(POWER)MAC  at this moment, OpenOffice Aqua is at beta level of development (here http://ooopackages.good-day.net/pub/OpenOffice.org/MacOSX/ the list of releases).

I tried OpenOffice Aqua since OOG68_m9 release and it worked well every time.  
(Version 2.4)
